Agreed. In fact, it will be virtually impossible to visit all those colleges between now and May 1.
Do not visit any WL colleges, as it will be a total waste of time. Just get rid of the ones you don’t feel drawn to. At most, it is only practical to visit three or four of these colleges, if you are lucky. Read about them on Niche, look at their social media, look at their virtual tours.
Disregard the “I might transfer” option when you are considering. It is not relevant to reality.
